EDWARD I. rEToW, or HYANNIS, MASSACHUSETTS, AssIGNoR or ONE-'RALF To NEWENGLAND GLASS WORKS, OF PROVIDENCE, RHODE ISLAND, A PARTNERSHIP POSED OFALBERT WEINER, ISAAC L. RICE, AND ALEXANDER ,WEINEBh NoNenARE STRUCTURE.

Application filed October 4, 1923. Serial No. 666,623.

To all whom t may concern.'

Be it known that I, EDWARD I. PEToW, a ycitizen of the United States,residing at Hyannis, in the county of Barnstable and State 6 ofMassachusetts, have invented certain new and useful Improvements inNonglare Structures; and I do declare the following to be a full, clear,and exact description ofD the invention, such as will enable othersskilled in 10 the art to which it appertainsto make and use the same.

My invention relates to light transmitting bodies such asheadlightlenses, glass or other transparent coverings for casingsinclosing intense light that is injurious to the eyes, etc., and moreparticularly to a body or structure of this character which will preventthe injurious glare of such lights without di1ninishing the amount oflight radiated from the bulb, burner, torch or the like and any re-Hector which may be associated therewith.

The principal object of my invention is to provide a simple, practicaland highly effec-v tive non-glare structure of this character,

which may be used as a headlight lens or for various other purposes,

The above and other objects are accomplished as hereinafter describedand in the accompanying drawing I have illustrated several forms ofpracticing the invention.

In the drawing Fi 1 is a face view of headlight lens embodymg theinvention;

Fig. 2 is a vertical cross-sectional view;

` and y Figs. 3 and 4 are sectional views through modied forms.

I have discovered that a substance known usually as essence dorient ororiental pearl 40 essence when applied to a transparent support such asa sheet of glass or sheet of celluloid will cause intense and glaringrays of light when transmitted through such treated sheet to lose thelintense glare without diminishing the volume of light. While this.essence dorienhrlwhigh is made from scales of certain fish, has beenused in the manufacture of articialpearls, it is my discovery that whenapplied to a transparent plate or sheet that the light transmittedthrough the same will be so subdued that the eyes will not be injuredorblinded and at the same time there will be no loss of effectiveness ofthe light. My invention is,

therefore, particularly adapted for use in ,connection with headlightlenses or cover.

ings of automobiles and in the drawings I have illustrated in Figs. 1and 2 the ordinary' circular headlight lens 1 consisting of atransparent glass plate having the coating 2 applied to one face of thesame. This coating may be applied by dipping, spraying or otherwise andvone or more coats maybe employed. If desired, the coating or coatingsmay be applied to both faces of the trans-y parent sheet 1a as indicatedat 2a in Fig. 3 or as shown in Fig. 4 the coating 2b may be in the formof a separate hn or sheet 2b arranged between two transparent sheets ofglass, celluloid or the like 1b. Obviously, the coating lmay be applieddirectly, to one face of the glass sheet as in Fig. 2 and a backing.-

or cover sheet of glass may be placed against this coating as suggestedin Fig. 4.

IVhile the essence dorient maybe applied to the transparent support inany suitable manner I prefer to apply it in the vehicle such as varnish,shellac, cotton laquer or the like and I preferably, but notnecessarily, use the following proportions, that is, 10 cu. cm.

of essence dorient to 12 fluid oz. of suitable vehicle. As indicatedabove, one or more coats may be applied to obtain varying thicknessesfor the coating, depending upon whether or not it is desired to reducethe volume oflight which will pass throu h the structure. However, Ihave foun that where a very thin coating is used there will be no lossof light when it passes through the Structure and that the blindingglare of an intense light will be entirely eliminated.

I claim:

transparent sheet andv a film associated 2. A non-glare structurecomprising a 1. A non-glare structure comprising a' transparent supportand a coating thereon comprising essence dorient and a vehicle.

3. A non-glare structure comprising a sheet of transparent material anda film associated therewith andl made from a compound consisting of amixture of 10 cu. cm. of essence dorient and 12 fluid oz. of a ve'-hicle such. as cotton lacquer; f

In testimony kwhereof I have hereunto axed my signature.

EDWARD I. PETOW.
